Elgaly said the victim was eating an ice cream and having a good time before a fight broke out.

“We’re used to fights, but nothing like this,” Elgaly said. “It was chaos.”

Lacertosa apparently ran outside and then somebody pulled a knife.

“It was a butcher’s knife,” Elgaly said. “I was told they put it on the side of the kid and they raised it up. He got cut pretty deep. That’s when he fell to the ground and everybody just started kicking him.”

Family members say Lacertosa’s half brother and fiancée, Bridgette Schneider, tried to save his life by performing CPR but it was too late.

Lacertosa was pronounced dead at Staten Island University Hospital.

Police won’t confirm witness accounts that it was an employee from the restaurant who pulled the knife but detectives did find the bloodied murder weapon in a dumpster not far from the scene, CBS 2’s Jessica Schneider.

Lacertosa leaves behind seven siblings, and the love of his life, who are now planning a funeral instead of a wedding.

There are several stories circulating on the media about what happened, why and who. Last I read was that the restaurant manager also pulled a gun that jammed and I’m still trying to figure out why they haven’t caught the guy who stabbed this groom. Confirmed report was that one of the brothers relieved himself on the side of the building. Why Why Why? All the remarks now can start with “hope you’re happy with yourself, looked at what you caused or what a bunch of hoods or what do you expect from Staten Island.” Well let’s give this family a break. A mother just lost her son and now has to bury him before her time. There is NO worse feeling. RIP young man and watch over your family from up in heaven.
